初二英语现在完成时练习题1.The poison in the waste p________ the river.（首

1.polluted (the poison in the waste是句子主语,这个句子是缺谓语,应该填动词.其实没有上下文的话用pollutes是可以的,但如果有上下文的话就要看时态了)
2.were(there be句型是采用就进原则,后面的people在这里是“人”的总称,应是person的复数形式,所以用were)
3.did,move to（从这个中文翻译来看应该是用过去时,move to 是固定搭配）
4.In the past,few people knew me.(“过去”一般可用in the past来表示,当然,把before放在句末也可做同意,“很少”在这里不用译为not many,这样会显得很Chinglish,直接用few就行了)
5.I lived together with my parents till 1990.(如果用until的话需换成过去完成时：I had lived with my parents until 1990.)
6.This place has been changed into an airport.(注意要用完成时时不要用短暂性动词,例如die,一个人总不能一直在死吧?）
7.joined,since（注意joint是一个adj,表示结合联合,而不是join的过去式）
8.How long（这个是叫你对时间的长短进行提问,所以用how long）
